Sillplate: NHIE Exam Prep

New in 5.0: 70 study lessons, 222 reference tables, 24 technical diagrams, and a question bank rewritten so the right answer never looks different from the wrong ones.

Failing the NHIE costs money and weeks you don't have. Sillplate gets you ready with 1,500 exam-style questions across all 11 NHIE content domains, every one explained, plus 70 study lessons and timed practice exams. Fully offline. No account.

WHY MOST PRACTICE APPS FLATTER YOU

You've seen the tell: the longest, most detailed answer is almost always the correct one. You score 85%, you feel ready, and none of that skill transfers on exam day — because the real thing doesn't hand you that clue.

We rebuilt every question in Sillplate to close that door. All four options are matched in length and sentence shape, and the wrong answers are real field mistakes: the wrong clearance, the adjacent component, the call that isn't the inspector's to make. There is nothing to pattern-spot. Your score reflects what you know, so you can trust it when you decide whether you're ready to book.

WHAT'S INSIDE

• 1,500 exam-style multiple-choice questions, weighted to match the published NHIE content outline
• All 11 content domains: structural, exterior, roofing, plumbing, electrical, HVAC, insulation & ventilation, interior, fireplaces & fuel-burning, analysis & reporting, professional responsibilities
• A written explanation on every question — the reasoning, not just the letter
• 70 study lessons (~100,000 words) — the full reference material behind the questions
• 222 reference tables: clearances, spans, wire gauges, ventilation ratios, temperatures
• Key-fact and field-condition callouts: what the inspector sees, what it implies, what the report says
• Adaptive practice that steers you into your weakest domains instead of the ones you already like
• Spaced-repetition review that brings missed questions back before you forget them
• Full-length timed exam simulation, plus a shorter mini exam for a quick check
• A readiness score that tells you where you actually stand
• State and jurisdiction licensing notes for all US states and several Canadian provinces

STUDY IN 10-MINUTE PIECES

Most candidates study around a job. Lessons run 5 to 8 minutes and practice sets pick up where you left off. Streaks, XP and levels keep the habit going — and Chip, a beaver who evolves and builds his lodge as you progress, gives you a reason to come back on the days motivation doesn't.

WORKS ANYWHERE, TAKES NOTHING

Everything runs on your device. Crawlspace with no signal, job site, subway, plane — it all works, every question, every lesson. No account to create, no sign-up, and nothing about your studying leaves your phone.

FIVE LANGUAGES

Interface in English, French, German, Spanish and Italian. Exam content stays in US English, because that is how the NHIE is administered — practising in the exam's language is part of the preparation.

WHO IT'S FOR

Candidates preparing for the National Home Inspector Examination, inspectors-in-training working through a course, and working inspectors wanting a fast refresher on clearances and spans.
